Patent number: 9492658Abstract: Various embodiments concern a guide catheter for delivery of an implantable lead within the coronary vein. Such a guide catheter can comprise a tubular body having a main lumen and at least one preformed bend. The tubular body can comprise a liner defining an inner surface, braiding circumferentially surrounding the liner, a jacket covering the braiding and defining an exterior surface of the tubular body, and a plurality of inflation tubes embedded within the jacket. The guide catheter can include a balloon mounted on the tubular body, each of the plurality of inflation tubes in communication with the balloon. The guide catheter can further include a hub providing access to the main lumen, the hub comprising a first port for introduction of contrast media into the main lumen and a second port in communication with the plurality of inflation tubes.Type: GrantFiled: November 14, 2013Date of Patent: November 15, 2016Assignee: Cardiac Pacemakers, Inc.Inventors: Brice L. Shireman, Brian R. Reynolds, Bruce A. Tockman, Pu Zhou, Henry J. Pepin

Patent number: 8535243Abstract: Medical devices and methods for making and using the same. An example medical device may include a metallic tubular member including a tube wall defining an inner diameter and having a wall thickness. The tubular member may have a plurality of slots formed therein. The tubular member may also include first portion having a first length. The tube wall may have a substantially constant wall thickness across the first length. The tubular member may also include a second portion having a second length. The tube wall may thin so that the inner diameter increases across the second length.Type: GrantFiled: September 10, 2008Date of Patent: September 17, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Brice L.

Patent number: 8002715Abstract: Medical devices and methods for making and using the same. An example medical device may include an elongate core member having a proximal portion and a distal portion. A polymer jacket may be disposed about at least a portion of the core member. The jacket may include an outer surface. A lubricious coating may be disposed on the outer surface of the jacket. A coil may be disposed about at least a portion of the jacket. The coil may have an outer surface and may include a first section and a second section. At least a portion of the outer surface of the coil along the first section may be flush with or recessed below the outer surface of the polymer jacket. At least a portion of the outer surface of the coil along the second section may protrude from the outer surface of the polymer jacket, may be free of the coating, and may define a region of decreased lubricity.Type: GrantFiled: May 30, 2008Date of Patent: August 23, 2011Assignee: Boston Scientific Scimed, Inc.Inventor: Brice L. Shireman
